I have three original deck hatches on my Contest 36k which are badly crazed. I cannot find any new hatches that would be a like for like fit for the apetures. Odd sizes - 520 x 510. I would need to fit a wooden plinth I believe but I just don't like the look of those. My question is has anyone any experience fo re-glazing deck hatches? There is company in the states online that offer this service but I can't find anything over here. Any ideas?
 
I used someone in Chandlers Ford who does this as a bit of sideline businesss. If this is convenient then I can try and find their details. Took about 2 weeks and charged about £100 for that size of hatch.
 
Are you a DIYer?. I did my own in my Nic 32 in Coruna 2 yrs ago, 2 hatches plus the 2 forward facing windows. Not as difficult as I thought it would be, I would say I did the four, cost about €150 for the acrylic, cut to shape, which I think is adequate and weathers better than Lexan, which is very uv and scratch sensative, cut out the old acrilic with a stanley type knife, clean v, very carefully, acetone, if you decide to do it yourself I will look up the sealant I used, it was very good. Mask off well, don,t take the film off the acylic, just enough to expose the rim that has to "see" the sealant. It,s not difficult.
 
Do the major window manufacturers use straight acrylic, tinted in my case? My concern is that hatches have to take weight and shock loads - waves crashing in etc. My present hatch windows have a lot of "give" in them - presumably this is a design feature, so I'd like to retain this when re-windowing.

I'm only have to do this 'cos the present windows have crazed so badly. For a few quid more is there a spec of plastic that is less prone to this defect?

Thanks for any help you can give.

The acrylic I used was 10mm and there is no flex/give, I don,t think its designed to flex, just cheaper!!! not as strong as lexan but I am perfectly happy and lexan has it,s drawbacks, I have used it before on the last boat. I would specify uv resistant when you buy the material, though I think the modern stuff is anyway. My old ones were nearly 30yrs old. Bill.
